Ortiz has not been charged, but is being held by state police in Millbury. A dark-colored SUV was seen in the area around the time Marcotte was killed, Early said.
Investigators reported that Marcotte likely fought back during the struggle with her assailant and that the murder would likely have sustained scratches or scrapes to their head, neck, hands, and upper arms during the attack. It was because Marcotte fought against her attacker that police were able to find him. Early said that he anticipates bringing a murder charge against Colon-Ortiz as the investigation progresses.
The announcement spurred a round of applause from attendees assembled more than eight months after Marcotte, a New York City native, disappeared while jogging not far from her mother's home in Princeton, about 60 miles west of Boston.
The DNA match linking Ortiz to the Marcotte case came back Friday afternoon.
Police have made an arrest in connection with the killing last summer of a 27-year-old Google employee as she was out jogging in broad daylight in MA. Early said Colon-Ortiz, who speaks limited English, has requested an attorney. Police said her body was naked and partially burned. She never returned, and her body was found that night in a wooded area about a half mile from her mother's house.
"Vanessa mentioned that she wanted to run Boston one day, so I thought doing it this year would be meaningful", McNiff said during a phone interview with Runner's World in March.
Authorities received thousands of tips on a dedicated line regarding Marcotte's case.
He is being held in police custody and will be arraigned in Leominster District Court.
